GENERAL DESCRIPTION  
The ADP3309 is a member of the ADP330x family of precision  
low dropout anyCAP voltage regulators. It is pin-for-pin and  
functionally compatible with Nationals LP2981, but offers  
performance advantages. The ADP3309 stands out from  
conventional LDOs with a novel architecture and an enhanced  
process. Its patented design requires only a 0.47 μF output  
capacitor for stability. This device is stable with any type of  
capacitor regardless of its equivalent series resistance (ESR)  
value, including ceramic types for space restricted applications.  
The ADP3309 achieves 1.2% accuracy at room temperature  
and 2.2% overall accuracy over temperature, line, and load  
regulations. The dropout voltage of the ADP3309 is only  
120 mV (typical) at 100 mA. This device also includes a current  
limit and a shutdown feature. In shutdown mode, the ground  
current is reduced to ~1 μA.  
The ADP3309 operates with a wide input voltage range from  
2.8 V to 12 V and delivers a load current in excess of 100 mA.  
The ADP3309 anyCAP LDO offers a wide range of output  
voltages.
